At least one portion of the container holder may include a photoluminescent material configured to convert the first emission to a second emission. The second emission may have a second wavelength longer wavelength than the first wavelength. Upon receipt of the first emission, the photoluminescent material may emit the light at the second wavelength to illuminate the container holder.

Referring to FIG. 1, a perspective view of a vehicle console 10 comprising a container holder 12 is shown in accordance with one embodiment of the disclosure. The container holder 12 may comprise a cupholder, beverage container, or any device configured to retain a position of an object within a vehicle. The vehicle console 10 may be incorporated in any portion of a passenger compartment of a vehicle, for example a center console, organizer, door panel, etc. The container holder 12 may comprise a lighting apparatus 14 comprising a light source 16 configured to excite a photoluminescent material disposed in at least one photoluminescent portion 18.

The container holder 12 is configured to provide a soft ambient lighting emitted from the at least one photoluminescent portion 18 of the container holder 12. In order to incorporate the soft ambient lighting in the container holder 12, the at least one photoluminescent portion 18 may be configured to emit light from various portions of the container holder 12. The at least one photoluminescent portion 18 may comprise a base portion 20, and in some implementations may further comprise at least one finger 22. The at least one finger 22 may extend outward into a container receiving cavity 24 formed by the container holder 12 and may be configured to secure a container disposed in the receiving cavity 24.

The light source 16 may be disposed beneath the base portion 20 and is configured to emit a first emission. The first emission comprises electromagnetic radiation in the form of light that is configured to excite the at least one photoluminescent portion 18. The first emission may comprise a first wavelength of light corresponding to a blue and/or near ultraviolet wavelength of light. In response receiving the first emission, the at least one photoluminescent portion 18 may become excited and emit a second emission comprising at least a second wavelength of light longer than the first wavelength. The second wavelength of light may provide for the second emission to be substantially more perceptible to the human eye relative to the first wavelength. In this way, the lighting apparatus 14 provides an ambient glowing light in the form of the second emission emitted from the at least one photoluminescent portion 18.

In the example illustrated in FIG. 1, the container holder 12 is demonstrated as a component of a center vehicle console 26. For purposes of illustration, the center counsel 26 further comprises a gearshift lever 28 and an actuator 30. Though demonstrated in a particular configuration, the container holder 12 may be configured for use in any portion of a vehicle. The container holder 12 may also be configured for use in various forms of vehicles including automotive vehicles, watercraft, airplanes, trains, buses, etc. to provide a cost-effective system to illuminate the container holder 12.

Referring to FIGS. 2A-2C, a photoluminescent structure 42 is generally shown rendered as a coating (e.g. a film) capable of being applied to a vehicle fixture, a discrete particle capable of being implanted in a vehicle fixture, and a plurality of discrete particles incorporated into a separate structure capable of being applied to a vehicle fixture, respectively. The photoluminescent structure 42 may correspond to the at least one photoluminescent portion 18 as discussed herein. At the most basic level, the photoluminescent structure 42 includes an energy conversion layer 44 that may be provided as a single layer or a multilayer structure, as shown through broken lines in FIGS. 2A and 2B.

The energy conversion layer 44 may include one or more photoluminescent materials having energy converting elements selected from a phosphorescent or a fluorescent material. The photoluminescent materials may be formulated to convert an inputted electromagnetic radiation into an outputted electromagnetic radiation generally having a longer wavelength and expressing a color that is not characteristic of the inputted electromagnetic radiation. The difference in wavelength between the inputted and outputted electromagnetic radiations is referred to as the Stokes shift and serves as the principle driving mechanism for an energy conversion process corresponding to a change in wavelength of light, often referred to as down conversion. In the various implementations discussed herein, each of the wavelengths of light (e.g. the first wavelength, etc.) corresponds to electromagnetic radiation utilized in the conversion process.

Each of the photoluminescent portions may comprise at least one photoluminescent structure 42 comprising an energy conversion layer (e.g. conversion layer 44). The energy conversion layer 44 may be prepared by dispersing the photoluminescent material in a polymer matrix 50 to form a homogenous mixture using a variety of methods. Such methods may include preparing the energy conversion layer 44 from a formulation in a liquid carrier medium and coating the energy conversion layer 44 to a desired planar and/or non-planar substrate of a vehicle fixture. The energy conversion layer 44 coating may be deposited on a vehicle fixture by painting, screen printing, spraying, slot coating, dip coating, roller coating, and bar coating. Additionally, the energy conversion layer 44 may be prepared by methods that do not use a liquid carrier medium.

For example, a solid state solution (homogenous mixture in a dry state) of one or more photoluminescent materials may be incorporated in a polymer matrix 50 to provide the energy conversion layer 44. The polymer matrix 50 may be formed by extrusion, injection molding, compression molding, calendaring, thermoforming, etc. In instances where one or more energy conversion layers 44 are rendered as particles, the single or multi-layered energy conversion layers 44 may be implanted into a vehicle fixture or panel. When the energy conversion layer 44 includes a multilayer formulation, each layer may be sequentially coated. Additionally the layers can be separately prepared and later laminated or embossed together to form an integral layer. The layers may also be coextruded to prepare an integrated multi-layered energy conversion structure. For clarity, the polymer matrix 50 comprising photoluminescent material may be referred to as the energy conversion layer 44 hereinafter to demonstrate that each may be similarly utilized to convert the first wavelength of light to at least a second wavelength.

Referring back to FIGS. 2A and 2B, the photoluminescent structure 42 may optionally include at least one stability layer 46 to protect the photoluminescent material contained within the energy conversion layer 44 from photolytic and thermal degradation to provide sustained emissions of outputted electromagnetic radiation. The stability layer 46 may be configured as a separate layer optically coupled and adhered to the energy conversion layer 44. The stability layer 46 may also be integrated with the energy conversion layer 44. The photoluminescent structure 42 may also optionally include a protective layer 48 optically coupled and adhered to the stability layer 46 or any layer or coating to protect the photoluminescent structure 42 from physical and chemical damage arising from environmental exposure.

The stability layer 46 and/or the protective layer 48 may be combined with the energy conversion layer 44 to form an integrated photoluminescent structure 42 through sequential coating or printing of each layer, or by sequential lamination or embossing. Alternatively, several layers may be combined by sequential coating, lamination, or embossing to form a substructure. The substructure may then be laminated or embossed to form the integrated photoluminescent structure 42. Once formed, the photoluminescent structure 42 may be applied to a chosen vehicle fixture.

In some implementations, the photoluminescent structure 42 may be incorporated into a vehicle fixture as one or more discrete multilayered particles as shown in FIG. 2C. The photoluminescent structure 42 may also be provided as one or more discrete multilayered particles dispersed in a polymer formulation that is subsequently applied to a vehicle fixture or panel as a contiguous structure. Additional information regarding the construction of photoluminescent structures to be utilized in at least one photoluminescent portion of a vehicle is disclosed in U.S. Pat. No. 8,232,533 to Kingsley et al., entitled “PHOTOLYTICALLY AND ENVIRONMENTALLY STABLE MULTILAYER STRUCTURE FOR HIGH EFFICIENCY ELECTROMAGNETIC ENERGY CONVERSION AND SUSTAINED SECONDARY EMISSION,” filed Jul. 31, 2012, the entire disclosure of which is incorporated herein by reference.

Referring to FIG. 3, the lighting apparatus 14 is generally shown according to a front-lit configuration 62. In this configuration, the light or a first emission 64 emitted from the light source 16 is converted to a second emission 66 by the energy conversion layer 44. The first emission 64 comprises a first wavelength λ₁, and the second emission 66 comprises a second wavelength λ₂. The lighting apparatus 14 comprises the photoluminescent structure 42 disposed on or in at least one photoluminescent portion. The photoluminescent structure 42 may be rendered as a coating and applied to a substrate 68 of a vehicle fixture 70, for example the at least one finger 22. The photoluminescent material may also be dispersed as a polymer matrix 50 corresponding to the energy conversion layer 44. In some implementations, the energy conversion layer 44 may further include the stability layer 46 and/or protective layer 48. In response to the light source 16 being activated, the first emission 64 is received by the energy conversion layer 44 and converted from the first emission 64 having the first wavelength λ₁ to the second emission 66 having at least the second wavelength λ₂. The second emission 66 may comprise a plurality of wavelengths λ₂, λ₃, λ₄ configured to emit any color of light from the photoluminescent portion 18.

In various implementations, the lighting apparatus 14 comprises at least one photoluminescent material incorporated in the polymer matrix 50 and/or energy conversion layer 44 and is configured to convert the first emission 64 at the first wavelength λ₁ to the second emission 66 having at least the second wavelength λ₂. In order to generate the plurality of wavelengths λ₂, λ₃, λ₄, the energy conversion layer 44 may comprise a red-emitting photoluminescent material, a green-emitting photoluminescent material, and a blue-emitting photoluminescent material dispersed in the polymer matrix 50. The red, green, and blue-emitting photoluminescent materials may be combined to generate a wide variety of colors of light for the second emission 66. For example, the red, green, and blue-emitting photoluminescent materials may be utilized in a variety of proportions and combinations to control the output color of the second emission 66.

Each of the photoluminescent materials may vary in output intensity, output wavelength, and peak absorption wavelengths based on a particular photochemical structure and combinations of photochemical structures utilized in the energy conversion layer 44. As an example, the second emission 66 may be changed by adjusting the wavelength of the first emission λ₁ to activate the photoluminescent materials at different intensities to alter the color of the second emission 66. In addition to, or alternatively to the red, green, and blue-emitting photoluminescent materials, other photoluminescent materials may be utilized alone and in various combinations to generate the second emission 66 in a wide variety of colors. In this way, the lighting apparatus 14 may be configured for a variety of applications to provide a desired lighting color and effect for a vehicle.

The light source 16 may also be referred to as an excitation source and is operable to emit at least the first emission 64. The light source 16 may comprise any form of light source, for example halogen lighting, fluorescent lighting, light emitting diodes (LEDs),organic LEDs (OLEDs), polymer LEDs (PLEDs), solid state lighting or any other form of lighting configured to output the first emission 64. The first emission 64 from the light source 16 may be configured such that the first wavelength λ₁ corresponds to at least one absorption wavelength of the one or more photoluminescent materials of the energy conversion layer 44 and/or polymer matrix 50. In response to receiving the light at the first wavelength λ₁, the energy conversion layer 44 may be excited and output the one or more output wavelengths λ₂, λ₃, λ₄. The first emission 64 provides an excitation source for the energy conversion layer 44 by targeting absorption wavelengths of the various photoluminescent materials utilized therein. As such, the lighting apparatus 14 may configured to output the second emission 66 to generate a desired light intensity and color.

In an exemplary implementation, the light source 16 comprises an LED configured to emit the first wavelength λ₁ which corresponds to a blue spectral color range. The blue spectral color range comprises a range of wavelengths generally expressed as blue light (˜440-500 nm). In some implementations, the first wavelength λ₁ may also comprise wavelengths in a near ultraviolet color range (˜390-450 nm). In an exemplary implementation, λ₁ may be approximately equal to 470 nm.

The blue spectral color range and shorter wavelengths may be utilized as an excitation source for the lighting apparatus 14 due to these wavelengths having limited perceptual acuity in the visible spectrum of the human eye. By utilizing shorter wavelengths for the first wavelength λ₁, and converting the first wavelength with the conversion layer 44 to at least one longer wavelength, the lighting apparatus 14 creates a visual effect of light originating from the photoluminescent structure 42. In this configuration, light is emitted from the photoluminescent structure 42 (e.g. the first photoluminescent portion 18) from locations of the vehicle 10 that may be inaccessible or costly to add conventional light sources requiring electrical connections.

As discussed herein, each of the plurality of wavelengths λ₂, λ₃, λ₄ may correspond to a significantly different spectral color range. The second wavelength λ₂ may correspond to the excitation of a red-emitting photoluminescent material having a wavelength of approximately 620-750 nm. The third wavelength λ₃ may correspond to the excitation of a green emitting photoluminescent material having a wavelength of approximately 526-606 nm. The fourth wavelength λ₄ may correspond to a blue or blue green emitting photoluminescent material having a wavelength longer than the first wavelength λ₁ and approximately 430-525 nm. The wavelengths λ₂, λ₃, λ₄ may be utilized to generate a wide variety of colors of light from the at least one photoluminescent portion 18 converted from the first wavelength λ₁.

Referring to FIG. 4, the lighting apparatus 14 is generally shown according to a back-lit configuration 72 to convert the first emission 64 from the light source 16 to the second emission 66. In this configuration, the lighting apparatus 14 may comprise an optic device 74 configured to channel the light at the first wavelength λ₁ substantially along the photoluminescent portion 18. The optic device 74 may be of any material configured to transmit the light at the first wavelength λ₁ substantially across the extents of a surface 76 of the optic device 74. In some implementations, the optic device 74 may comprise a polymeric material configured to provide a refractive index such that the light at the first wavelength is transmitted consistently throughout the surface 76.

The backlit configuration also comprises an energy conversion layer 44 and/or photoluminescent material dispersed in a polymer matrix 50. Similar to the energy conversion layer 44 demonstrated in reference to the front-lit configuration 62, the energy conversion layer 44 may be configured to be excited and output the one or more output wavelengths λ₂, λ₃, λ₄ in response to receiving the first emission 64. The one or more output wavelengths λ₂, λ₃, λ₄ correspond to the second emission 66. The plurality of wavelengths λ₂, λ₃, λ₄ of the second emission 66 may be configured to emit any color of light from the photoluminescent portion 18 in response to the excitation of the energy conversion layer 44. The color of the light corresponding to the second emission 66 may be controlled by utilizing a ratio of photoluminescent materials as discussed herein.

In the backlit configuration 72, the photoluminescent portion 18 may be at least partially light-transmissive and configured to transmit electromagnetic radiation from the light source 16 outward from the lighting apparatus 14. In such a configuration, a concentration of the photoluminescent material in the energy conversion layer 44 may be configured to convert a first portion 78 of the first emission 64 to the second emission 66 while allowing a second portion 80 of the first emission 64 to pass through the photoluminescent portion 18 and remain at the first wavelength λ₁. As illustrated in FIG. 4, the first portion 78 of the first emission 64 is converted to the second emission 66, while the second portion 80 passes through the energy conversion layer and remains at the first wavelength λ₁. The second portion 80 of the first emission 64 may be directed to additional photoluminescent portions and converted to a third emission. For example, the second portion 80 may be directed to a photoluminescent portion of the at least one finger 22 as discussed in reference to FIG. 5.

Referring to FIG. 5 a schematic view of the lighting apparatus 14 for the container holder 12 is shown. In this exemplary implementation, the light source 16 is configured to generate light to illuminate the container holder 12 in both a front-lit configuration 62 and a back-lit configuration 72. In this implementation, a first photoluminescent portion 90 may correspond to the back-lit configuration 72, and a second photoluminescent 92 portion may correspond to the front-lit configuration 62. By illuminating both the first photoluminescent portion 90 and the second photoluminescent portion 92, the lighting apparatus 14 provides for an efficient lighting system operable to illuminate multiple portions of the container holder from a single, conveniently located light source.

The first photoluminescent portion 90 may comprise the base portion 20. The base portion 20 may comprise any material operable to transmit a portion of the first emission 64 at the first wavelength λ₁ through the base portion and into the container receiving cavity 24. The base portion may comprise any material or polymer matrix comprising a concentration of photoluminescent material configured to convert the first portion 78 of the first emission 64 to the second emission 66 and allow the second portion 80 of the first emission 64 to pass therethrough. In some implementations, the base portion 20 may comprise a semi-transparent polymer mat having the photoluminescent structure 42 molded therein.

The second photoluminescent portion 92 may comprise the at least one finger 22 or as demonstrated in FIG. 5, a plurality of fingers 94 configured to secure a container disposed in the receiving cavity 24. In some implementations, the second photoluminescent portion 92 may comprise the energy conversion layer 44 applied as a coating and may also comprise at least one photoluminescent structure disposed in a polymer matrix used to form or coat the plurality of fingers 94. The second photoluminescent portion 92 may be configured to convert the first emission 64 at the first wavelength λ₁ to at least a second wavelength λ₂ longer than the first wavelength λ₁.

In some implementations, the second photoluminescent portion 92 may be configured to emit a third emission 96. The third emission 96 may be configured to emit light having a substantially similar color to the second emission 66 and may also comprise a corresponding photoluminescent materials and proportions similar to the first photoluminescent portion 90. In some implementations, the second photoluminescent portion may be configured to emit the third emission 96 having a different color than the second emission 66. As discussed in reference to the at least one photoluminescent portion 18, the first and second photoluminescent portions 90, 92 may be configured to emit the second emission 66 having a first color and third emission 96 having a second color different from the first color. The color of the second emission 66 and the third emission 96 may be manipulated by utilizing photoluminescent materials in a variety of proportions and combinations to control the output colors and corresponding wavelengths of light to illuminate the container holder 12.

Though the second photoluminescent portion 92 is described in detail in reference to the plurality of fingers 94, the second photoluminescent portion 92 may correspond to any feature disposed in or proximate to the container holder 12. For example, the second photoluminescent portion may comprise a ring configured illuminate in response to the first emission 64 disposed on a sidewall 98 of the container holder 12, a pivoting arm configured to secure a container, or any other feature. Further, each of the features may be configured to emit light in different colors. For example, the base portion may be configured to emit the second emission 66 having a green colored light, a first finger 100 of the plurality of fingers 94 may be configured to emit a third emission having a yellow colored light, and a second finger 102 of the plurality of fingers 94 may be configured to emit a fourth emission having a white colored light. In this way, the lighting apparatus 14 may be utilized to produce any combination of colors for a variety of ambient lighting effects.

In an exemplary implementation as demonstrated in FIG. 5, the lighting apparatus 14 may be configured to provide ambient lighting in the container holder 12 as disclosed. In various implementations, the container holder 12 may be configured to receive a plurality of containers in a plurality of container receiving cavities including a first receiving cavity 104 and a second receiving cavity 106. In this configuration, the lighting apparatus 14 is configured to illuminate the first receiving cavity 104 and the second receiving cavity 106 from a centralized light source 108. In this way, the disclosure may provide for further efficiency by illuminating the plurality of container receiving cavities from the centralized light source 108.

In operation, the light source 16 (e.g. the centralized light source 108) is configured to emit the first emission 64 into the optic device 74. The optic device 74 is configured to disperse the first emission 64 consistently along a surface 110 of the first photoluminescent portion 90 of each of the container receiving cavities 104, 106. Upon receipt of the first emission, the first photoluminescent portion 90 is configured to convert the first portion 78 of the first emission to the second emission 66 to illuminate the base portion 20. The concentration of the photoluminescent materials in the first photoluminescent portion 90 is configured to allow the second portion 80 of the first emission to pass through the base portion 20 and pass into the container receiving cavities 104, 106 to illuminate at least one feature comprising the second photoluminescent portion 92.

In some implementations, the second portion 80 of the first emission 64 may pass through each of the container receiving cavities 104, 106 to the plurality of fingers 94. The plurality of fingers 94 may comprise the second photoluminescent portion 92. Upon receipt of the second portion 80 of the first emission 64, the second photoluminescent portion 92 may become excited and illuminate each of the fingers 94. In this configuration, the lighting apparatus 14 is operable to provide ambient lighting for the container holder 12 from a cost effective, centrally located light source. Further, the lighting apparatus 14 is configured to illuminate the container holder 12 in a wide variety of colors and combinations to provide lighting that may be customized based on any preference. The various implementations of the systems and methods disclosed herein provide a novel approach for illuminating a container holder for a vehicle and may be utilized to provide attractive ambient lighting in a variety of settings.
